Trouble with MongoDB on Ubuntu!

Tonight I've been setting up an Ubuntu server to run a MongoDB. MongoDB is a noSQL document database, that promises scalability. I'm new to noSQL databases, but already I'm finding them liberating compared to the rigid schema based traditional DBs.

I'm also fairly new to Ubuntu. I used to develop on Sun linux and silicon graphics but that was a long time ago, and Ubuntu is very different from the xterm vi based system I was used to.

So, I installed MongoDB using the Ubunto software repository. Which worked well, and was simple to do.... and then I started playing with MongoDB. To aid testing, playing etc MongoDB provides a javascript shell that can be used as a stand alone client of the database. Which I played with and became familiar with how to put a document into a DB, which is incidentally, really simple.

The trouble started when I tried to put a document into the database using a simple Java client, using the mongo java driver (here). I could not get this to work. The connection to my server failed to connect. I wracked my brains and searched stack overflow, and finally found this excellently written site that prompted me to uninstall the Ubuntu repository version of MongoDB and re-install using the Debian apt (advanced package tool). This worked a treat, and I now have a java test program that persists data to a remote MongoDB sat on an Ubunto VM running in Oracle's virtual box. Sweet!

Many thanks to Russell Bateman over at JavaHotChocolate!

Android logging put to bed.

I've been developing an android application recently, and I have had to scrabble around more than I should have in order to get logging working correctly so here's what I've learned. How to get logging working; The basics. Android has a Log class that you can use to make log entries. You can find that here; https://developer.android.com/reference/android/util/Log.html Here's an example of a log entry made from an Activity #import android.util.Log; class MyActivity{     private static final String TAG = "MyActivity";     @Override     protected void onCreate(Bundle savedInstanceState) {         Log.v(TAG, "savedInstanceState contains " + savedInstanceState.size() + " mappings");         ......     } } The Log.v call makes a 'verbose' log entry. Log levels (in increasing order of 'importance' are;  ...

Using an Ubuntu VM to connect to a VPN using juniper network connect.

Recently I've been using Ubuntu 12.04 running in a VirtualBox VM to connect securely to a VPN using Juniper Network connect. I've been doing this for years with a windows VM, but have recently worked out how to do it from Ubuntu. The benefits of using Ubuntu for this task are; No licensing requirements for OS. Smaller footprint for VM. - Windows 7 VM footprint was 120 MB Private Working Set. Ubuntu is as low as 70 MB Private Working Set. I haven't found any drawbacks yet. Step 1. Create an Ubuntu 12.04 LTS desktop 32bit virtualbox machine. It is important that you choose the 32 bit platform as the 64 bit version will install a 64 bit java, and juniper network connect won't work with this. If you have an existing 64 bit 12.04 install that you want to use see  here  for a work around. Step 2 Ensure openjdk-6-jdk and icedtea-6-plugin are installed by running this command from the Ubuntu VM's command line; sudo apt-get install openjdk-6-jdk ic...

The Simple Way to Create an AM Authentication Node Project

What's that all about? ForgeRock's Identity Platform Access Management introduced Authentication Trees for preview in version 5.5. Version 6.0 will see Authentication Trees and Nodes become an integral part of the product. This blog post will help you quickly and easily create a Authentication Tree Node project using Maven Archetypes. About Authentication Trees and Nodes Authentication trees provide fine-grained authentication by allowing multiple paths and decision points throughout the authentication flow. Authentication trees are made up of authentication nodes, which define actions taken during authentication, similar to authentication modules within chains. Authentication nodes are more granular than modules, with each node performing a single task such as collecting a username or making a simple decision. Unlike authentication modules, authentication nodes can have multiple outcomes rather than just success or failure. You can create complex yet customer-friendly...
